My Christmas present-

9. Well. yeah. And a Hundai Sonata can do 0-60 in 3.8 seconds. Just takes a little work . . .

In practical terms digital cameras don't do IR. Sticking a filter on won't do it. Pour enough money on it and it might do UV as well or even X-ray.

Back in the days of film ya' had to set up, focus, adjust the focus for IR shift, install the filter and guess at the exposure because exposure meters don't register outside the visible spectrum. It took a lot of trial and error to learn how much IR was available.

For those wondering about the big deal with IR, it penetrates the surface of some subjects. Leaves, human skin and some other surfaces become translucent with an ethereal character. Water and glass are completely opaque and the clear sky goes black. Portraits take on a mystic air and skin seems to glow.

It's also good for super surveillance work at night. Put an IR filter on a flash and on the lens and by God you can see in the dark--can't focus for $#it but nobody knows you're there!

'Course this is all film stuff from the dark (room) age and B&W at that. T'was a most frustrating experience.
